near 'the lower ends thereof sre'pivoted two rods 5 and 6. SecuredV kto the rock-shaft 4 are a pair of rods 8 and 10, having weights i2 go and 14 suspended from the outer ends there of. -Pivoted'to the inner ends of these rods are `the V1;latterrir-standards 15 and 18, veach of whichj's provided with a platform 16 and 20;

on the'npyerend thereof. The rod 5 consti-" q 5 A tutes a pivot or an arm 25, and the rod 6.' constitntesfs, pivot for the arm 22, the ends of the arms 25 and 22 being provided with one of the ecctrodes, such as the carbon or zinc, of an eieetricbattery, as represented at roo 23Yand 26 and the ends of these arms lare comimd Vs-eoil 27. The latticini-stende' arde {Sfnd 18 are connecte at their levier'n end withxtliese 'arms by 24 :and V2S andhave connected therewith jeiitabie conductors A and B, as'shown in Figure l is a perspective View of Vthe :ina-YL j ltre construction thus far described'oonstitntes the Weighing mechanism for the pack? i xo ase 85 parts may be varied at will and within the construction of an ordinary operative scale, so as to provide an ollicient and sensitive weighing apparatus.

f 'lnc means for operating the weighing mechanism comprises two concentric shafts' 32 and 33, the l'ornnfr being tubular and inclosing the latter and having secured thereto at onel end an arm 34 and at its other end an arm Q0, while the latter has a similar arm 35 secured at one end and an arm 88 secured at its other end. This shaft 33 is ournaled at one end in a standard 30, secure to the bast` 1 of the wcighin mechanism, and the other end is journalc in an arm 84, adjustably mounted in a standard 81, as seen in Fig. 4. The standard 81 rises from a base 82 and is provided with a slot 86, into which a setscrew 85, screwed on the end of the arm 84,

o may be adjusted, this adjustment permitting the concentric shafts 32 and 33 to be raised or lowered and brought into operative relation with a plate 78, carried on the end of i a drive-shaft 74, as will be me` e fully expia-ined hereinafter. The edge of the plate 78 is provided with a projection 80, which. is adapted to engage with the pins or rollers 89 and 92 on the en( s of the arms 88 and 90, and when thus engaged the shafts 32 and 33 will be rocked axially and trip the arms 34 and 35 on the other ends thereof'. Then eitherof the pins 89 or 92 rides off of the projection 8U, the arms of the shafts 32 and 33 drop down on the edge of the plate 78, and the weight of these arms, together with the Weight of the arms 34 and 35, will be suHicient to reset the weighingmechanism-that is, engage with the arms 22 or 25 to lower the platforms 16 and 20; but if the Weight of these elements is not suilicient to restore the platforms to their oising position after the package has been lled springs C C may be connected with the arms 88 and 90, as shown: The arm 35 on the end of the shaft 33 instead of engaging directly with the bar 22 may con- `tact with a spring-arm 36, secured to the platform 1 and extending across and above .the bar 22, so that the shaft 33 will have a yielding rocking motion when it operates to 5o j ower the platform 16 of the weighing mechanism.

The drive-shaft 74 is driven by a shaft '65, which is journaled in suitable hearings 66, sccured to a base or shelf D at the to of the machine. 0n this shaft 65 is a pu ley 68, which is connected with any source of power -by a belt 68, and onthe end of the shaft is a worm-screwO, which meshes with a wormble 40. The table 4() is adapted to convo;I the ackages and is provided with twocircum crcntial rows of openings 44 and 45, thil openings of one row boing arrangrd in .stag-- gered relation with thc o ienings of the other row and each openingr preiorably having annu-- lar grooves 43 therea'rrnind, the grooves serving as seats for the flange or projecting rim of the cans or packages, and thereby insuring a proper centering of the can over the openings, which the table travels are brought. into vertical alinernent with thc dischargetube of the fillin mechanism hereinafter to be described an which are also in vertical alinem'ent with the platforms 16 and 20 of the Weighin mechanism, so that the platforms may e projected through the o enings above the table and elcvafe the pac agc when it is to be filled.

The filling mechanism comprises va case or receptacle 49, which is mounted in any suitable manner above the table and into which the material to be packed is introduced. Connected` to the` bottoni of the receptacle 49 is a vertical tube 51, the lower end of which fits into an opening 56 of a cylindrical casing or shell 50. (Shown in section in Fig. 2.) In the bottom of this casing 50 are two openings 52 `and 54, from which the material is alternately discharged. Revolubly mounted within the casing 50 is a conveyer-tube 55l which is provided with two openings 57 and 5P., arranged in vertical alinement with the Jpenings 52 and 54 of the casing, but out of horizontal alinernent with each other, so that when one of the openings 58 of the tube is in alinement with the opening 52 of the casing the other openin 57 of the tube will be out of alinement witv the opening 54 of the casin Y, and vice versa, whereby when the materia is dischar ed from the opening `52 the opening 54 wil be closed. Journaled in the end plates of the tube is a screw-conveyer shaft 62, hav-ing the usual screw 60 for advancing the material toward the dischargeopenings, and on the end of this'shaf't 62 is a pulley 63 ,which is driven by a belt 63. The tube 55 has a limited axially oscillatory movement in the casing` 50, and such movement may be imparted thereto by a series of links and levers which are operated .by the driveshaft. This operating mechanism consists of a link 115, one end of which is ivoted to an ann 118, ,which is secured to t e tube 55 and extends through a slot in the casing 50, as shl'iwn in Fig. 1, and the other end is pivoted to one arm ofa bell-crank lever 111, ulcrmed upon a bracket' 110, which is mounted on` a` shelf or frame 103 of the machine. To the other arm of the hell-crank lover is pivoted a linkV 114, the lower end .of which is in. turn pivoted'to the bent end 105 of a rock-shaft .08, journaled in a hanger 102, which is also secured to the shelf 103 of th(` frame. The ends of ,the rock-shaft HS are lCO ITC

the cam rotates with the drive-shaft the arm 100 of the rock-shaft 98 will be engaged elterna-tely with the lug and the recess to bring the respective openings 57 and 58 of theiiliing-tube into alinement withV the epeningsg and 54 of the easing, and during the time that the ermlOG is between the lug 96 and the recess 96* both of the cpenin s 57 and 58 of the filling-tube will be out of a nement Wi th the .cliseherge-opein'nv 52 54, so that the mete- Spilled upon the table between the tripping o the erm G.

, during the filling operation the parts are et a standstill; but when the drive-shaft again starts the arm 100 is immedietel disengaged from the lug 96 by means of t e spring 7, which exerts an upward pressure thereon,

' and `vhen thus disengaged the lever-endssA link connections have been moved to rock` the filling-tube '55, so es to bring the openings 54 and 57 out of registering relation the lling-tube has not rotated sufficiently to the o eninV 52 end 58 into registering relation ith t e parte ofthe lin mechanism in these positions the drive-s aft rotetes, end through the pinionv the table is-V ladvanced to bring the next cen in vertical elinement with the discharge-opening 'e2 of this movement the; arm 100 o the rook-shaft 98 is in engagement the easih and during with' Ythe Het orllevel surface of the eers# wheel 95, but is permitted to a ein he trippedV or drawn u werdly when ie recess '96*l comes into ehnement with the end of the erm. It will be seen that this-last tri ping action of ltheerm 100 is upwerdl in a. llrection o po site to that caused by t e'engligeietv o 'the lug 96, and therefore the lever-snd-link een-Y necticns ereV moved in en opposite direction, so as to continue the oscillation of the filling-V tube' and Bring the opening 58 into eline-V ment with the diseharY e-opening 52.

The particular clutch which I employ lor locking and unlocking the driveshntt T4- and the shaft 65 'is illustrated in detail in Figs. El and 1t) and conmrisesl an u pcreylindrieal element 122, which is key@ to the drive shaft 74 and which is provided with a. eircuinferental groov'e 1-23 Vand a transverse slot in which a key or in 125 tits. The lower element 12() of tie clutch is loose upon the shaft 74 and preferably consists.y of two disks, the lower one of which constitutes a wormgear for the worm-shaft 70, while the upper disk, which is secured to thol lower disk, has a series oi notches or recesses 120", formed in its upper edge, the notched surv face lying contiguous to the lower lace ol thel disk 122, so that the lpin 125 may drop into engagement with one of the notches and lock the lower geared clement to the driveshaft l74, as Shown in li'ig. Si. Cooperating with-this clutch are a pair oi clutch-levers 133, which are secured together near one end hy a contractile spring 137, and the other ends of4 the levers project forwardly and outwardly to form a fork whichstraddles tue member 122 ol'v the clutch with the arms normally engaged wit iin the groove 123A 'lhc arm 132 olI the clutch-lever is heYeled on its up )er surfaceat its end, as at 135, and the en of the arm 131` is formed with au oll'set or inward projection which is heveled in an opposite. direction, as at 136, se that .the slot or recess 126 in the clntcli-pin will he permitted-to ride up the inclined beveled sur l lare and onto the arms, andwhenthus elevated the clutclepin will hc disengaged from the notch `ol" the loose member 12t, and the driw'slm 't 711 will then he disengald from the pon'ei-lml't o5, since the nielnher 120 will imply rotate upon the shaft 74 without im l pin-ting motion to the latter. The arms 131 :ind 1;!'2 ol' the lever are pivoted in a standzud 1311.) ata point in the rear of the contract ile spring |217, so as to permit the forked ends ol the arms to lie expanded against the i Lietion ol' the spring, the arms swinging horixontally, as will he clear from the illustration in Fig. l, such spreading action emanating from the re.'irwzn'd movement of the spreaderhar 151, which hears upon the arms at the point where the) merge outwardly,I all of which will be, more fully set forth in the statement of the operation.

The operation ma)Y he stated as follows: The operator ma load the tahlc with empty packages l'roinone side thereof and at the same time remove the filled 'iackagea and presuming the parts to hc in t le position inlimited in Fig. l with the arm S8 of the shaft will in engagement with the lug 80 on the plate TN and the arm B5 on the other end of the `halt disengaged from the har 22, so that the plat torni is elevated through one ot' the openthe tahle 4U are at a standstill, but the arm 10() ot' the rock-sliaft Q8 is engaged with thc" ings in thc conveyor-tube is in alinement with one of the discharge-openings in the casing 5t), and the material is hcing discharged into a package supported on the platform. During this filling operation the element 23, carried hy theI rod 22, is drawn out of the Solution in the hatterysjar and the circuit in the conductors A and B is broken, so that the i magnet is deenergized and the clutch-levers are in engagement with the annular groove 123 ir the clutch meniher 122, but the c ut-chpin 1 5 has traveled o onto the arm 132 of thc clutch-lever and tis-engaged the geared element' 12() l'roni the element 123. As soon as enough material has been dischargedinto the pnekzige to conntcrlmlancc the weight l2 ot thi` weighing mechanism the platform 16; with the package thereon, is lowered and the' package liecomes seated in the annular groove 4:1, which surrounds the opening in the tahle. As heteroI stated, the continued downward movement ,of the platform is caused hy the weight of the arms 35 and 8S, augmented hy the action ofthe spring C, `and the arm 315, through the medium of the spring- 'arm 36, will immerse the element 23 int the hatte r \'-j er, thereluY making the circuit in the conductors A and Il and energizing the elec-` tromagnet 1.40, and the movements of its ele ments, through thcvllexiblc connection 148, will draw the har. 153 and ue spreader-bai l 154 rearwardly to spread the' arms of the ings 44 in the table, the t rive-shaft 74 and 95 log .16 on the cam 95, so that one ofthe open- IOO IIO

in the casing 50. During the rotation ofthe.

shaft 74 the pin 'in the end of the arm 88 has become disenga ed from the projection 80 of the late 78, an this action took place upon the initial rotation of the shaft 74, which was practically instantaneous with the immersion Y of the element 23 into the battery-jar. When the projection 8f) reaches the'pln in the end of the arm 99, the shaft 32 is rocked and the arm 34 on the other end thereof is disengaged from the rod 25, so as to ermitthe platform 20, connected therewith), to be proected through one of the openings 45 to elevate the package over the same. synchronously with the disengagement of the pin in the end of the arm 88 With the pr jection 80 the erm 100 of the rock-shaft 98 was also disengaged from the lug 96 of the cam 95, and Ythe spring.

7 moved the arm 100 upwardly to pull upon the link 115 and through its jointed connections rotated the conveyer-tube-55 su` ciently to cnt off the discharga'and the discharge remains cut ofi during the rotation of the cam, which isenga ed with the end of the arm 100. However, t e notch or'rentrant portion 96ay in the cam Will permit the arm 100 to continue its upward movement when these two elements are invalinement, and the size of the cam and the pla-te` 78 are such as to permit the rejection 480 to be en aged with the pin" in t e end of the arm Vil wen the re entrant portion 96* isinalinementwith' the arm '100. With the parts in such positions I' in the casing 50, and the material will be the conveyor-tube has been rotated aufliciently to bring the other o ening therein into alineinent with one ofthe ischarge-.openings emptied into the package supported on the platform 20. Vshaft 74 to bring the filling mechanism and the weighing mechanism into operative relation wit each other the clutchfpin 125, which had been permitted to drop down into a notch A`in the element 120, was carried around with the rotar)r cliitch,and when it reached the inclined face' 13 6 on the offset end of the arm- 131 of the clutch-.lever the element 120 was' a t ain dsenga ed from the element 1 22 and e drive-sha t stop ed.A vThe filling operation continues, unti the package Ycontains, enooghlmateriai to counterbalance theweiglit 14 o package will cause t e platform 20 to'descend and immerse the element 26 into the solutionY the weighin mechanism, when the in the battery-jar 28, lcompleting the circuit During the rotationg--of theA in the conductors A and B and againenergizing the magnet, which, as before stated, operates the s reader-bar 154 to spread the arms of the c utoh and permit the pin'25 thereof te a ain be engaged with one of the notches in tlie loose element 120.

It will he seen that the'operation is continuoes and that each package contains a uniform amount of material, which is automatically filled, Wei hed, and conveyed away from the llng mechanism.
